Question

Check two easy questions please?

Answer 1

What are the amplitude, period, phase shift, and midline of f(x) = −4 cos(3x − π) + 1?

Amplitude: −4; period: pi over 3; phase shift: x = pi over 4; midline: y = −1
Amplitude: 4; period: pi over 3; phase shift: x = pi over 4; midline: y = 1
Amplitude: −4; period: 2 pi over 3; phase shift: x = pi over 3; midline: y = −1
Amplitude: 4; period: 2 pi over 3; phase shift: x = pi over 3; midline: y = 1<-----

Answer 3

amplitude is a positive number
forget 1 and 3
